Do all men ignore the details?

You're paying for a service that's supposed to include quality items, his using poor quality is actually stealung from You. Most of my paternal relatives are in housing construction one way or another, from electrician, to drywall, foundation layment, framing, roofing, as well as windows and doors too, several cousins do remodeling/renovations for both upgrade and insurance work. You need to go straight to your local licensing board and put in an official report and complaint, as well as talk to a lawyer to get a discovery to find out exactly how much he's ripping you off, and to sue. His bid should have included listing specific material brands and items, their cost, and his specific labor.
